WVhen the bag isfiiied the operator i" ii draw the two aprons back by grasping the two fixed ment parts With-out depa t handles thereon, thus allowing the bag to slip oil from the aprons and drop down so that its entire Weight is supported at its base. In view of the fact that the springs at the bottom are not made sufficiently strong to support the entire Weight of the bag, the bag will drop down, giving room for the operator to tie it as indicated in Fig. l. lt-

will be observed that thus the bag is supported both at the top and bottom, the springs being so designed that a portion of the hood Will be carried by the aprons and a portion by the springs at the bottom.

In the drawings 1 have shown my device as applied to a machine specially adapted to filling valve bags, and l have used the term filling tube. It will be understood, however, that my device need not be limited to a device practicable only for a valve bag filling machine, and the term tube need not in any sense be limited to a tube such as that adapted to enter and fill valve bags. It will be quite evident that this tube might be an kind of a tune it mi ht be inclined or even vertical instead of horizontal, it might be a tube designed particularly for the filling of open mouth bags, it might take any desired or necessary form or position or be made of any suitable material, and my cap or hood might be provided to conform. to, but not in any sense depart from the spirit of my invention and claims.

I claim:

l. In a bag filling machine a filling tube and a collapsiole bag supporting hood mounted thereon, said hood being made up I of two sections pivoted one upon the other and entirely closed at the top, and yielding means for forcing said pivoted sections apart about their pivotal points to distend the mouth of the bag.

2. In a bag filling machine a horizontally disposed bag filling tube, means comprising a hood inclosing the discharge end of said tube for completely closing the open. mouth of a bag and means for supporting a bag upon said hood.

3. in a bag filling machine a hood made up of a pair of aprons always inclined one to the other and pivoted together along one edge, a sleeve carried by one of said aprons and a bag filling tube upon which said sleeve is mounted.

one apron being in contact with and slidable upon the opposed members on the other.

5. In a bag filling machine a hood made up of a pair of aprons inclined one to the other and pivoted together along one edge, a sleeve carried by one of said aprons and a bag filling tube upon which said sleeve is mounted, each of said aprons having in- Wardly bent end members, the members of 'one apron being in contact with and slidable upon the opposed members on the other, said sleeve being mounted in one of said aprons, the opposed member being slotted to engage the sleeve.

6. In a bag filling machine a hood made up of a pair of aprons inclined one to the other and pivoted together along one edge, a sleeve carried by one of said aprons and a bag filling tube upon which said sleeve is mounted, each of said aprons having inwardly bent end members, the members of one apron being in contact with and slid able upon the opposed members on the other, handles fixed each upon one of the opposed pairs of sides and means for holding said handles together.

7. In a bag filling machine a fillingtube andan entirely closed bag supporting two part cap carried thereby, said two parts in pivotal engagement one with the other and closed at their 8. in a bag filling machine a filling tube and a closed bag supporting two part cap carried thereby, said two parts in pivotal engagement one With the other near their upper ends, yielding means resisting the appreach of said parts one to the other at their lower edges.

9. In a bag filling machine a filling tube and a closed bag supporting two part cap carried thereby, said two parts in pivotal cngagement one with the other near their upper ends, yielding means resisting the ap proach of said parts one to the other at their lower edges, and means for locking said parts together.

10. In a bag filling machine comprising a horizontally disposed filling tube, a two part- A-shaed hood mounted thereon the two e I 1 o I 7 parts ()1 said hood being pivoted one upon the other. said hood being open at the bottom and having means about said open bottom tor engaging the open end of the yielding means for pressing the two pivoted hood parts outwardly to distend the bag.
